Answer:
600
Step-by-step explanation:
Well, first you need to make a proportion which will be
x is what we need to find
6,000 is the total people who voted
10% is the percent of 18 to 29 years old
and 100% represents the circle graph because all circle graphs equal 100%
First, we use the cross multiply method, for instance, 6,000×10=60,000
Next, divide 60,000÷100 which is 600.
Therefore there are 600, 18 to 29 year olds who voted in the election.
70%=70/100=7/10
what you do is shade 7 of the squares and say that is 21
now each square is worth the same
so 21/7=3
each square is worth 3
10 squares
3 times 10 is 30
the number is 30
see diagram
